v WEATHER-STRIP.

. ipeciflcation of Letters Patent. Patented Apr. 20,1920.

Application filed March 20,-1917. Serial No. 155,981.

at Troy, in the county of Miami and State of Ohio, have invented certainnew and useful Improvements in Weather-Strips, of which the following isa specification.

My invention relates to swinging sashes,

swinging doors or other closures, and more particularly to automobile.wind shields, and especially to a weather strip or sealing strip foreffectively'closing the intervening crevice between the sash door orwind shield, and its support or the frame of the window or otheropening.

The object. of the invention is to simplify the structure as well as themeans and mode of operation of such devices whereby they will not onlybe cheapened in construction, but will be more efficient in use,positive and uniform in operation, and unlikely to get out of repair. I

A further object of the invention is to provide a form of overlappingjointwhich will obviate any crevice and compensate for any lack ofuniformity of the engagement of the parts.

With the above primary and other incidental objects in view as will morefully appear in the specification, the invention consists of thefeatures of construction, the

parts and combinations thereof, and the mode of operation, or theirequivalents, as hereinafter described and set .forth in the claims. p

In the preferred embodiment of the invention illustrated in the drawing,Figure portion of a sash or wind shield frame together with a portion ofa window or opening frame or wind shield support and the interposedweather strip.

Fig. 2 is a sectional plan view showing the parts in disconnected oropen position.

Heretofore it has been unusual to provide a weather strip normallyprojecting into the path of a swinging door or other closure member,which is adapted to be engaged with such member as it approaches itsclosed portion, and bent laterally or placed under tension whereby theweather strip through its elasticity is caused to bear upon the swingmember or if carried by the swinging member is caused to bear upon theframe to close the intervening crevice. It is found however in practicethat through uniformity of the, tension of the flexible strip, andvariation of the surface engaged thereby, the

strip will not always conform closely to the contour of the engagedsurface. This is partlcularlytrue after a long period of usage. In thecase of automobile wind SlllGldS it is particularly desirable that allcrevices be closed. To insure such complete closure, 1s one of theprimary objects of the present invention.

Referring to the drawing 1 is the sash frame which is provided on itsouter or marglnal edge with a tongue or bead 2 formlng at each sidethereof a shoulder or rabbet 3. The wind shield support 5 or frame ofthe window or. opening is provided with a groove or channel 6 in whichis seated a flexible weather strip. This weather strip is preferably ofrubber composition or other resilient material. It may be constructed ofan suitable flexible or yielding material. Viewing the strip in crosssectional form it comprises an enlarged base portion 7 from whichprojects a tongue or flange 8, prefeu ably though not necessarily wedgeor V shaped. The base portion? is preferably though not necessarilyinclosed in a channel or housing 9 which is clenched at its oppositeside over the lateralportions or shoul-- said tongue or flange normallyprojects into the path of the swinging element, whether same be a windshield, a window sash or dooras indicated by dotted lines. As theswinging member approaches the limit of its stroke it engages theflexible flange or tongue 8 and bends the same laterally. The swingingmember continues this movement until the lateral shoulder or rabbet 3 ofthe sash frame rides over the top of the flexible flange or tongue 8 andthe bead or tongue 2 of the sashframe engages a lateral face of theweather strip flange 8. If the strip is of uniform composition andflexibility 8 of the weather stripI will likely conform owever shouldthere thereto throughout.

between the sash and be any inequalities window strip whereby the edgeof the flange 8 will not adhere or conform closely to the contour of thesash, the resultin crevices will be closed by the enga ing 0 the bead ortongue 2 with the side 0 the flange 8 on a line somewhat removed fromits edge. Thus the flange 8 and the tongue 2 not only overlap but theflange 8 has at its edge a lineal contact bearing on the shoulder orrabbet 3 in addition to its parallel lineal .contact with the bead ortongue 2 thus affording two separated parallel lines of contact indifferent planes. Further more the overhang of the shoulder or rabbet 3beyond the edge of the flange 8 serves to protect any interveningcrevice against the entrance of wind or rain. While the bead or tongue 2has been-shown in the drawings upon the sash frame and the flexibleweather strip mounted upon the support or window opening frame, it willbe understood that therelation of these parts may be reversed and thebead or tongue 2 may be stationarily located upon the face or openingframe while the flexible weather strip ma be carried by the swingingelement. he cross sectional form of the flexible strip may be varied ora thin flat strip may be substituted.

From the above description it will be apparent that there is thusprovided a device of the character described, possessing the particularfeatures of advantage before,

enumerated as desirable but which obviously is susceptible ofmodification in its form, proportion, detail construction or arrangementof parts, without departing from the principle involved or sacrificingany of its advantages. While in order to comply with the statute, theinvention has'been described in language more or less specific as tocertain structural features, it is to be understood that the inventionis not limited to any specific details, but that the means andconstruction herein described comprise but one mode of putting theinvention into effect, and the invention istherefore claimed broadly inany of its possible forms ormodifications within the scope of theappended claims.

Having thus described my invention I claim: j

1. The combination with two relatively movable bodies of a flexibleflange or bead upon one of the bodies and two contact faces upon theother body angularly arranged in relation one to the other to formarabbet, said flexible flange being extended into the path of movement ofthe other movable body and flexed by its engagement trant angle of therabbet to be simultane-. ously engaged by the same side of the flexibleflange or bead upon relative movement I of said odies.

2. The combination with two relatively movable bodies of a flexibleflange'upon one of the bodies, and a rigid bead upon the other bodyforming withthe main portion thereof a shoulder or rabbet, the faces ofthe rabbet and the flexible flange being so proportioned and arranged inrelation one with another that upon relative movement of the bodies theflexible flange will engage one face of the rabbet with a wiping contactuntil it abuts upon the second face of the rabbet thus filletingthe'angle of said rabbet, substantially as specified.

3. The combinatlon with two relatively movable bodies of a bead carriedby one of the bodies at a oint removed from the edge thereof, and aexible flange carried'by the other body, said flexible flange beingadapted to engage the beaded body with a wiping engagement intermediatethe bead and the edge thereof and to simultaneously engage the bead upona line of contact separated from that of its engagement with the mainportionof the beaded body.

4. The combination w th two relatively movable bodies of a flexibleflange upon one of said members and a bead upon the other of saidmembers, said flange and bead tane'ously engage the bead and saidlateral extending contact face of the member car- 7 rying the beadsubstantially as specified.

5. A weather strip construction applicable to two relatively movablemembers com prising a flexible flange upon one of said members adaptedto'fbe flexed laterally by. its engagement with the other member and anengaging portion upon the other member so shaped and arranged as toengage the convex side of the flexed flangeiupon independent "separatedlines of contact.

6. The combination with two relatively movable members capableofadjustment to and fro the one past the other, of a flexib le bead uponone of the members and a rigid bead upon the other member, extendinginto overlappin' relation, said flexible bead being adapte toengage-either side of therigid bead according to the direction ofmovement of the movable member and tion therewith to permit the movementof one member past the otherv member.
